SAC (seismic analysis code) has been installed on the student Macs in the department or you can request it online for your own computer. To install it yourself, follow the instructions in the README file you get in the download.
To get sac on the student Macs to work for you, use the terminal application, and open a new window. Then copy over a file that tells the system where sac can be found by typing into that terminal window: cp ~gscadmin/.cshrc .
This file only needs to be copied once. The following two commands however need to be run every time you want to use sac. Make sure you are running a suitable environment by typing into the terminal window: /bin/csh
Then tell the system where it can find sac by typing: source ~/.cshrc
Now everything has been set up and if you want to run sac, simply type: sac
And it should show up like this:

SAC>
And it is now waiting for your commands.
To get familiar with sac, go through the tutorial. First read through the initial information and then try out some of the examples.
More resources are available from the IRIS SAC website, including a searchable archive of user questions and answers.
This Youtube video also should be useful (just skip over the parts about Antelope).
For beginner tutorials, please email cppsegstudentchapter@gmail.com with the subject "UNIX, SAC, GMT Tutorials." These tutorials are set up similar to a quiz format, where each question asks for the next step, and mostly go over the basics. IRIS and Dr. Mike Brudzinski of Miami University (OH) has set up these tutorials and is allowing access to students that are interested.
